Pain Under Fingernail When Pressed

Pain under the fingernail when pressed usually results from injury, infection, or nail disorders affecting sensitive tissues beneath the nail.

Understanding the Anatomy Behind Fingernail Pain

The fingernail is more than just a protective covering; it’s a complex structure made up of several layers and tissues. The nail plate sits atop the nail bed, which is rich in blood vessels and nerve endings. Beneath the nail bed lies the phalanx bone, and surrounding it are soft tissues that cushion and protect. When pressure is applied to the fingernail, any disruption to these delicate structures can trigger sharp or throbbing pain.

The sensitivity under the nail comes primarily from the nail bed and the surrounding skin folds, which contain numerous nerve endings. Even minor trauma or inflammation in this area can cause significant discomfort. Understanding this anatomy helps explain why pain under fingernails can be so intense despite the small size of the affected area.

Common Causes of Pain Under Fingernail When Pressed

Pain beneath a fingernail when pressed can arise from various causes, ranging from minor injuries to serious infections. Pinpointing the exact reason requires careful observation of accompanying symptoms such as swelling, discoloration, or pus formation.

1. Trauma and Injury

One of the most frequent culprits behind fingernail pain is trauma. This includes:

Crushing injuries: Slamming a finger in a door or dropping a heavy object on it can cause blood vessels under the nail to rupture.
Subungual hematoma: This is bleeding beneath the nail plate that creates pressure and intense pain.
Nail bed lacerations: Cuts or tears under the nail can cause sharp pain when pressed.

Trauma-induced pain usually appears quickly after injury and may be accompanied by visible bruising or swelling.

2. Infections

Infections around or under the fingernail are common causes of tenderness and throbbing pain.

Paronychia: An infection of the skin around the nail fold often caused by bacteria or fungi leads to redness, swelling, and pus formation.
Felon: A deep infection in the fingertip pulp that causes intense pain and swelling.
Onychomycosis: Fungal infections inside or beneath nails cause thickening, discoloration, and sometimes discomfort.

Infected nails often feel painful when pressed due to inflammation and increased pressure within confined spaces.

3. Nail Disorders

Certain chronic conditions affecting nails may also result in pain under pressure:

Nail psoriasis: Causes pitting, thickening, and separation of nails leading to discomfort.
Ingrown nails: When edges of nails grow into surrounding skin causing irritation and pain.
Nail tumors or cysts: Though rare, growths beneath nails can cause localized tenderness.

These disorders often develop gradually but can produce persistent sensitivity to touch.

The Role of Subungual Hematoma in Fingernail Pain

A subungual hematoma occurs when blood pools beneath the nail due to damaged capillaries after trauma. This trapped blood presses against sensitive nerves in the nail bed causing sharp, throbbing pain—especially noticeable when pressing on the affected area.

The color of a subungual hematoma typically changes over time:

Stage	Description	Color Appearance
Immediate	Fresh bleeding under nail plate	Bright red or dark maroon spot
1-3 days later	Blood begins clotting and drying out	Purple to black discoloration
7+ days later	Nail starts growing out; hematoma moves distally	Darker shades fading toward edge of nail

If untreated, pressure buildup from large hematomas can lead to permanent damage to the nail matrix or secondary infections.

Treatments for Pain Under Fingernail When Pressed Due to Injury

Addressing pain caused by injury depends on severity:

Mild bruises: Applying ice reduces swelling; elevating hands limits blood flow; over-the-counter painkillers help manage discomfort.
Larger subungual hematomas: Medical drainage via trephination (creating a small hole in nail) relieves pressure quickly.
Nail bed lacerations: Require professional cleaning and suturing; antibiotics may be necessary if infection risk is high.
Pain management: Topical analgesics along with oral NSAIDs provide relief during healing phases.

Prompt treatment minimizes long-term damage while easing acute pain effectively.

Tackling Infections Causing Nail Pain: Medical Approaches

Infections demand targeted therapies based on causative agents:

Bacterial paronychia: Warm soaks combined with oral antibiotics like cephalexin usually resolve symptoms within days.
Fungal infections (onychomycosis): Require prolonged antifungal treatments—topical agents like ciclopirox or oral medications such as terbinafine are common choices.
Pus drainage: Abscesses around nails might need incision for pus removal alongside antimicrobial therapy.
Avoiding recurrence: Maintaining dry hands and avoiding trauma reduces infection risk significantly.

Ignoring infections often worsens symptoms leading to chronic pain and potential deformities.

The Impact of Nail Disorders on Fingertip Sensitivity

Chronic conditions affecting nails alter their structure causing discomfort:

Nail psoriasis: Inflammation disrupts normal growth causing pits, ridges, thickening—all contributing to sensitivity when pressed.
Ingrown nails: The ingrowth irritates surrounding skin triggering localized inflammation with sharp pain upon touch.
Cysts/tumors: Although rare beneath nails, these lesions create pressure on nerves leading to persistent tenderness even without external trauma.
Treatment options vary widely—from topical steroids for psoriasis to surgical removal for ingrown nails or cysts—highlighting importance of professional diagnosis.
